If you are tight on money DO NOT get a chameleon, give it back immediately. They are very expensive exotic animals, between their enclosures, lights, suppliments, and food it can be hundreds to thousands of dollars. What type of chameleon is it? You'll need a small mesh cage to start, then a large one as it grows, as an adult probably a 2x2x4 mesh. You'll need a reptisun 5.0 UVB light (30ish bucks right there) a basking light (which can get expensive since you replace the UVB every 6 months), crickets for the larger ones are 15 ish a day as adults, or dubia roaches, you'll need to mist EVERY day, 3 times a day ish, for 2 mins at a time, the entire cage, you'll need to buy specific plants that are safe for the chameleon, ALOT of plants are needed, you need suppliments, calcium without d3 everyday, you lightly dust the bug, (expensive, since you have to buy it online), calcium with d3 2x a month, and multivitamins 2x a month, (another 30ish dollars just for a small container), the enclosure itself can be 100 bucks or more, the fecal exams are 100+, not to mention vet visits incase it gets sick. No substrate, use paper towels at the bottom. I'm sure people are linking you with things as we speak.
